Pull retainer emergency safety switch

Abstract

A pull retainer emergency safety switch includes a plastic housing and a switch module, wherein, the plastic housing has a push block device and a pull retainer piece has a ring retainer. The ring retainer abuts on a rotating handle configured in an upper portion of the push block device, and causes an underside of the rotating handle to abut on a triangular push block, and a bottom surface of the triangular push block is utilized to abut on a top surface of another triangular push block, thereby enabling a side surface of the second triangular push block to abut upon a push button of the switch module. When pulling on the pull retainer pieces the rotating handle with an anticlockwise rotating force produced that actuates the triangular push block and enables a horizontal displacement thereby pressing the switch module to actualize rapid cutting off of power supply.

1. A pull retainer emergency safety switch comprising a plastic housing and a switch module, and characterized in that: the plastic housing comprises a push block device and a pull retainer piece, wherein a ring retainer is configured on a front end of the pull retainer piece, and the ring retainer abuts on a rotating handle configured in an upper portion of the push block device, which causes a lower portion of the rotating handle to abut on a triangular push block, and a bottom surface of the triangular push block is utilized to further abut on a top surface of another triangular push block, thereby enabling a side surface of the second triangular push block to abut upon a push button of the switch module. 
   
   
     2. The pull retainer emergency safety switch according to  claim 1 , wherein the rotating handle configured on the upper portion of the push block device is provided with lugs and a pin connecting portion, moreover, an outer side wall of the pin connecting portion is provided with a locating hole. 
   
   
     3. The pull retainer emergency safety switch according to  claim 2 , wherein a locating column is disposedly configured on a bottom portion of the plastic housing, and a spring is disposedly configured on a bottom portion of the locating column; a top extremity of the locating column is utilized to correspondingly catch within the locating hole of the rotating handle. 
   
   
     4. The pull retainer emergency safety switch according to  claim 1 , wherein a locating column is disposedly configured on a bottom portion of the plastic housing, and a spring is disposedly configured on a bottom portion of the locating column; a top extremity of the locating column is utilized to correspondingly catch within the locating hole of the rotating handle. 
   
   
     5. The pull retainer emergency safety switch according to  claim 1 , wherein an actuator and two sets of electric terminals are configured interior of an insulated body of the switch module, wherein the electric terminals are respectively configured on an upper portion and a lower portion of an inner side of the insulated body, moreover, respective contact points of the two sets of electric terminals face toward a central portion of the insulated body, and two contact connecting bars penetrate and are thereby configured interior of the actuator; contact points of the upper contact connecting bars face upward toward corresponding contact points of the upper electric terminals, while contact points of the lower contact connecting bars face downward toward corresponding contact points of the lower electric terminals; a top extremity of the actuator is a push-button, and a spring is configured on a bottom extremity of the actuator.
